According to multiple sources with inside access to the band, Steven Tyler & Company are very disappointed in the sales of their newest album Music From Another Dimension, so much so that it’s driving a stake right through the heart of Aerosmith.

Their currently Global Warming Tour has 10 dates remaining and none of the venues are sold out as of yet. Adding to the friction is the meager sales of their latest effort, their first album with new material in over a decade.

A source told Page Six of the New York Post, “The band isn’t really talking. Aerosmith’s record came in fifth after Taylor Swift, ‘Now That’s What I Call Music: Volume 44,’ Rod Stewart’s ‘Merry Christmas, Baby’ and Ne-Yo’s new release. Pretty bad for their first release in a decade. No dates on the current tour are sold out. Meanwhile, LaPolt [Tyler’s manager] is doing a reality-show pilot instead of focusing on Tyler’s career, and his career needs help.”

A second source confirmed the turmoil to the Post, and added, “Tyler is very unhappy about the reception of the album, and is blaming Columbia. Let’s face it, since Aerosmith fired manager Tim Collins, and John Kalodner as their A&R guy, they were never able to capture the magic from their ’80s comeback. Tim kept them clean and sober and invested their money, making them millions.”

A spokesman for the band denied the claims, insisting that Aerosmith is fine. Are you buying it?
